Reducing AquaClear Flow

Has anyone ever had to decrease the outflow of an AquaClear? If so, how did you go about it. I have seen ideas of rigging a plastic cup or sponge to where the water flows out creating the "waterfall".

The reason I want to do this is because in my 7.5 gallon tank with an AC20, the flow that the water is creating overpowers my Salvinia floaters pushing them into one corner and making it so that the floaters are bunched up, and some fully submerged which is not good.

Google the water bottle trick. As long as the resulting output comes out both sides of the baffle, your floaters should get some more even circulation.

A planted spillway will help drastically. I have an aq70 on a 20l with a dwarf puffer. Overkill, yes. But, it's better then the stupid 10 gallon topfin hob that was there previously. I bought mesh from ac Moore, cut to size, sandwiched moss between them, and hooked it to the spillway. It also acts as additionally bio filtration but does also hold onto mulm that can cause cloudy water after restarting the hob. Sorry, the pic is upside down.

Done. Works like a champ.

But I do like the idea of a planted spillway, and feel like that will look a whole lot nicer than a piece of plastic bottle. But for a quick fix, the bottle worked great.

I wonder what drilling a few holes in the output would do? Also, extending the intake tube would reduce the flow somewhat.
